First, I would like to thank my tutor, Eberhard Grummt, for giving his feedback at every phase of my work and sharing his writing experiences of thesis. From every discussion with him, I can always get useful information to help my thesis proceed.\\


I would also like to thank Prof. Dr. Alexander Schill and SAP research: CEC Dresden, for providing me this interesting topic.\\


My thanks also go to Thorsten Karrer, for his complete and easy to use template for thesis writing.\\


And finally and most importantly, I would like to thank my parents Nanzhen Liu and Jiale Li and my girlfriend Ying Wang. Without their love and supports during my study in Germany, I can not achieve where I am now.\\
